RF Exposure Safety StatementSAFETY INFORMATION

Your wireless handheld portable transceiver contains a low power transmit-ter. When the Push-to-Talk (PTT) button is pushed, the transceiver sendsout radio frequency (RF) signals. In August 1996, the Federal Communica-tions Commission adopted RF exposure guidelines with safety levels forhand-held wireless devices.This device is authorized to operate at a duty factor not to exceed 50% (thiscorresponds to 50% transmission time and 50% reception time).WARNING: To maintain compliance with the FCC’s RF exposure guidelines,this transmitter and its antenna must maintain a separation distance of atleast 1 inch (2.5 centimeters) from your face. Speak in a normal voice, withthe antenna pointed up and away from the face at the required separationdistance.If you use a headset accessory for this radio, with the radio worn on yourbody, use only the STANDARD HORIZON belt clip for this transceiver, andensure that the antenna is at least 1 inches (2.5 centimeters) from your bodywhen transmitting.Use only the supplied antenna. Unauthorized antennas, modifications, orattachments could damage the transmitter, and may violate FCC regulations.

Congratulations on your purchase of the HX270E! Whether this is your firstportable marine VHF transceiver, or if you have other STANDARD HORIZONequipment, the STANDARD HORIZON organization is committed to ensur-ing your enjoyment of this high-performance transceiver, which should pro-vide you with many years of satisfying communications even in the harshestof environments.

We appreciate your purchase of the HX270E, and encourage you to readthis manual thoroughly, so as to learn and understand the capabilities of theHX270E fully.

ABOUT VHF MARINE RADIOThe radio frequencies used in the VHF marine band lie between 156and 158 MHz with some shore stations available between 161 and 163MHz. The marine VHF band provides communications over distancesthat are essentially “line of sight” (VHF signals do not travel well throughobjects such as buildings, hills or trees). Actual transmission range de-pends much more on antenna type, gain and height than on the poweroutput of the transmitter. The approximate distance a portable 5W radiomay communicate is about 5 miles in if there are no obstructions (build-ings, hills etc.) restricting line of sight transmission.

Attention in Case of UseThis transceiver works on frequencies which are not generally permitted.For frequency allocation, apply for a licence at your local spectrum man-agement authority. For actual usage con-tact your dealer or sales shop in order toget your transceiver adjusted to the allo-cated frequency range.

ceiver on.2. Press the SQL key, then press the [ ] key until the

SQL level is 00.3. Turn up the POWER/VOLUME CONTROL knob until

the noise or audio from the speaker is at a comfort-able level.

4. Select a channel that has no signal being received (no one is transmit-ting on the channel) and where only noise is heard.

5. Press the SQL key, then press the [ ] key and stop immediately afterthe noise disappears. This condition is known as the “Squelch Thresh-old.” If the squelch is set to a higher level, weak signals may not bereceived.

6. To change channels, press the [ ] or [ ] key.7. The LCD and keypad are illuminated for 5 seconds when any key is

pressed. The lamp automatically turns off in 5 seconds.8. To “lock” the channel so that it is not accidentally changed, hold down

the H/L key for about one second. This locks the [ ] and [ ] buttonsand all the front panel controls except the H/L, PTT and SQL keys. The“ ” symbol will appear on the display to indicatethat the keypad is locked. Hold down the H/L key forabout one second to unlock the keys. The “ ” sym-bol will disappear from the display.

HX270EPage 14

5.3 TRANSMISSIONNOTE

Never key the transceiver without an antenna connected, as this maycause damage to the transceiver.

1. Perform steps 1 through 7 of the RECEPTION discussion above.2. Before transmitting, monitor the channel and make sure it is clear.3. For communications over short distances, press the H/L key until “ ” is

displayed on the LCD. This indicates Low power (approximately 1 Watt).NOTE

Transmitting on 1 Watt prolongs battery life. Low power (1 Watt)should be selected whenever possible.

4. If using Low power is not effective, select Medium power (2.5 Watts) orHigh power (5 Watts) by pressing the H/L key until“ ” (Medium power) or “ ” (High power) is dis-played.

5. When receiving a signal, wait until the incoming signal stops before trans-mitting. The transceiver cannot transmit and receive simultaneously.

6. Press the PTT (Push-To-Talk) switch to transmit. The “TX” indicator isdisplayed during transmission.

7. Speak slowly and clearly into the microphone. Hold the microphone about½ to 1 inch away from your mouth.

8. When the transmission is finished, release the PTT switch.

5.4 TRANSMIT TIME - OUT TIMER (TOT)

The HX270E is capable of PC programming TRANSMIT TIME - OUTTIMER (TOT) by a dealer. Contact your dealer for further details.

While the PTT switch is held down, transmission time is limited to 5 minutes.This prevents prolonged (unintentional) transmissions. About 10 secondsbefore automatic transmitter shutdown, a warning beep sounds from thespeaker. The transceiver automatically switches to the receiving mode, evenif the PTT switch is held down. Before transmitting again, the PTT switchmust first be released, then pressed again. This Time-Out Timer (TOT) pre-vents a continuous transmission that would result from an accidentally stuckPTT switch.

HX270E Page 15

5.5 USA, CANADIAN, AND INTERNATIONAL BANDS1. To change the operating band (channel set) of the transceiver, hold down

the 16/9 key and press the DW key. The band will change from USA, toInternational, and to Canadian with each press.

2. “USA” appears on the LCD for the USA band, “INTL”appears for the International band, and “CAN” ap-pears for the Canadian band.

5.6 SCANThis transceiver provides a special “Scanning Memory Bank” which allowsyou to designate certain channels for inclusion in a “loop” which will bescanned at high speed. If an incoming signal is detected on one of the chan-nels in the scanning loop, the radio will pause on that channel, allowing youto listen to the incoming transmission.1. Select the desired channel to be included in the scanning loop using the

[ ] or [ ] key.2. Press the MEM key to store the channel into the

transceiver’s scanning memory. “MEM” will be dis-played on the LCD.

3. Repeat steps 1 and 2 for all the channels to bescanned.

4. To delete a channel from the transceiver’s scan memory, press the MEMkey again while the memorized channel is displayed. “MEM” will disap-pear from the display.

5. All channels programmed remain in the transceiver’s scan memory evenif the power is turned off.

6. Press the SQL key, then press the [ ] or [ ] key until background noiseis eliminated.

7. To start scanning, press the SCAN key. The scan proceeds from thelowest to the highest programmed channel number and stops on chan-nels when a transmission is received. Scanning will resume when thesquelch closes after the incoming signal disappears at the end of thetransmission.

8. To stop the scan, press the SCAN, 16/9, or DW key.

HX270EPage 16

5.7 PROGRAMMABLE PRIORITY SCANThe priority scanning feature allows the radio to scan while also keepingwatch on a particularly important “priority channel.” The following channelscan be set as the priority channel: 16, 09, and Preset Channels 1 through 8(Preset Channels are described in section 5.13).

1. To set the priority channel, hold down the 16/9 key and press the MEMkey. The channel will change from 16 to 09 to Preset 1 to Preset 2 toPreset 3 to Preset 4 to Preset 5 to Preset 6 to Preset 7 to Preset 8 witheach press of the MEM key. The displayed channel will be set as thepriority channel when the 16/9 key is released.

2. For priority scanning, hold down the SCAN key during normal scanning.Scanning will proceed between the memorized channels and the prioritychannel. The priority channel will be scanned after each programmedchannel. “P” is shown on the left side of the channel number during pri-ority scanning.

3. As an example of priority scanning, let us say that channels 06, 07, and08 are memorized in the transceiver’s scan memory. Priority scanningwill proceed in the following sequence:

[CH06] [Priority Channel] [CH07] [Priority Channel] [CH08] [Priority Channel] [CH06] [Priority Channel] ……

4. Even when the transceiver stops and listens to the signal of a programmedchannel, the transceiver will “dual watch” between this channel and thepriority channel. Therefore, your priority watching of the designated chan-nel is not compromised when the scanner has paused on an active channel.

5.8 DUAL WATCHThe Dual Watch feature allows the radio to watch for a transmission on thepriority channel and another selected Marine channel until a signal is re-ceived. The priority channel is determined per the discussion in section 5.7“PROGRAMMABLE PRIORITY SCAN” as described previously.

1. To start the Dual Watch feature, select a channel to be dual watchedwith the priority channel and press and hold in the DW key. The radiochecks the priority channel for voice traffic every onesecond. A small “DW” icon will be shown blinking onthe left of the display during scanning.

2. To cancel the Dual Watch feature, press the DW key.

HX270E Page 17

5.9 EMERGENCY (CHANNEL 16 USE)Channel 16 is known as the Hail and Distress Channel. An emergency maybe defined as a threat to life or property. In such instances, be sure thetransceiver is on and set to CHANNEL 16. Then use the following proce-dure:

1. Press the PTT (push-to-talk) switch and say “Mayday, Mayday, May-day. This is , , ” (your vessel’s name).

2. Then repeat once: “Mayday, ” (your vessel’s name).3. Now report your position in latitude/longitude, or by giving a true or mag-

netic bearing (state which) to a well-known landmark such as a naviga-tion aid or geographic feature such as an island or harbor entry.

4. Explain the nature of your distress (sinking, collision, aground, fire, heartattack, life-threatening injury, etc.).

5. State the kind of assistance your desire (pumps, medical aid, etc.).6. Report the number of persons aboard and condition of any injured.7. Estimate the present seaworthiness and condition of your vessel.8. Give your vessel’s description: length, design (power or sail), color and

other distinguishing marks. The total transmission should not exceed 1minute.

9. End the message by saying “OVER”. Release the PTT (push-to-talk)switch and listen.

10. If there is no answer, repeat the above procedure. If there is still noresponse, try another channel.

11. To recall the previously-selected channel, press the 16/9 key again.

5.10 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)Channel 16 may be used for initial contact (hailing) with another vessel.

However, its most important use is for emergency messages. This channelmust be monitored at all times except when actually using another channel.

It is monitored by the U.S. and Canadian Coast Guards and by other ves-sels. Use of channel 16 for hailing must be limited to initial contact only.Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radio traffic, congestion on channel 16resulting from its use as a hailing channel can be reduced significantly inU.S. waters by using Channel 9 as the initial contact (hailing) channel fornon-emergency communications. Here, also, calling time should not exceed30 seconds but may be repeated 3 times at 2-minute intervals.

HX270EPage 18

Prior to making contact with another vessel, refer to the channel charts inthis manual, and select an appropriate channel for communications afterinitial contact. For example, Channels 68 and 69 of the U.S. VHF Charts aresome of the channels available to non-commercial (recreational) boaters.Monitor your desired channel in advance to make sure you will not be inter-rupting other traffic, and then go back to either channel 16 or 9 for your initialcontact.

When the hailing channel (16 or 9) is clear, state the name of the othervessel you wish to call and then “this is” followed by the name of yourvessel and your Station License (Call Sign). When the other vessel returnsyour call, immediately request another channel by saying “go to,” the num-ber of the other channel, and “over.” Then switch to the new channel. Whenthe new channel is not busy, call the other vessel.

After a transmission, say “over,” and release the microphone’s push-to-talk(PTT) switch. When all communication with the other vessel is completed,end the last transmission by stating your Call Sign and the word “out.” Notethat it is not necessary to state your Call Sign with each transmission, onlyat the beginning and end of the contact.

Remember to return to Channel 16 when not using another channel. Someradios automatically monitor Channel 16 even when set to other channelsor when scanning; see your Owner's Manual.

5.11 OPERATING ON CHANNEL 13Channel 13 is used at docks, bridges and for maneuvering in port. Mes-sages on this channel must concern navigation only, such as meeting andpassing in restricted waters. In emergencies and when approaching blindriver bends, High power is allowed. Pressing the H/L key will change thepower output from 1 Watt ( ) to 5 Watts ( ); if pressed again, 2.5 Watts( ) will be selected. When the PTT switch is released, the transceiver willrevert to Low power. Press the H/L key again if you need High power on asubsequent transmission.

5.12 OPERATING ON CHANNEL 67When channel 67 is used for navigational bridge-to-bridge traffic betweenships, High or Medium power may be used temporarily (in the USA band) bypressing the H/L key. When the PTT switch released, the transceiver willrevert to low power.

HX270E Page 19

5.13 PRESET CHANNELS (1 ~ 8): INSTANT ACCESSEight user-assigned channels can be programmed for instant access.

5.13.1 Programming1. Hold down the PRESET key, and press the [ ] or [ ] key (repeatedly, if

necessary) until the desired channel number (from among the regularoperating channels) is displayed.

2. With the desired channel number displayed, release the PRESET key.The “1” notation will appear on the LCD display for 1 second, indicatingthat the displayed channel is now saved in the PresetChannel “1” position.
